If the goal is PhotoReading, that is where I would start. Then you are focusing specifically on what you want. The other Paraliminals and courses would augment the goal. You get the Memory Supercharger with the course. You also get a coupon for Personal Genius at a reduced price.
I would say get the PR course. Order Personal Genius once you have the PR course. Use Memory Supercharger and Personal Genius in conjunction with your PR efforts. This will give you a sense for how the Paraliminals work and for how they can help with your quest. As you make satisfactory progress with PR, you might branch out to other courses.
